Can Hot Days Affect Your AC Unit?

The Effect of Hot Days on your AC unit

The AC unit is the device in your home that is supposed to take care of the hot days. However, most AC units are adversely affected by hot days. The heat, airflow, and humidity during a hot day affect the way that the AC unit operates.


The unit operates in two different environments; the temperature within the house and the temperature outside of the house. The units are supposed to keep the inside of the house cool by transferring heat to the outside and also ensuring that the heat is not transferred back in through the AC unit. During the very hot days, a higher level of heat is getting into your house through windows and through the door. The AC unit does double the work on such days because the air outside is hotter and so it has to transfer the heat inside, that is as a result of direct sunlight through the window panes, outside where the level of heat is higher. It is harder because it has to reject air from the outside also. The higher the temperatures on the outside, the harder the AC has to work to keep the house cool. For example, an AC unit in Texas has a very difficult task due to the levels of heat in the State.


The AC unit is also adversely affected by the levels of humidity in the air. When the levels of humidity are quite high, the AC unit tends to do more work because it has to get rid of the dampness in the house. The cooling capacity of the unit comes into play during this time and if it is not at the standard required, then the results will be evident. The room will be very hot and damp because the unit will not be able to function properly and may need an AC unit repair.


Airflow is another factor that affects the way the AC unit operates within your house. The unit is as successful as its ability to circulate air from the house to the outside. When the circulation of the air is blocked then it will not work in the best way possible. Plants that are near the condenser on the outside may be the main source of blockage for the system. If they grow too close to the condenser then it will not work in the best way possible. It is always advisable to have about one foot always around the AC unit. The poor airflow may lead to an increase in the temperatures of the oiling system of the condenser. The heightening of the temperature leads to the faster breaking down of the oil in the oiling system making it less efficient. AC unit repair should be done regularly to ensure that the airflow is in perfect condition to avoid faster oil breakdown rather than the 15 years it was intended to last. The airflow efficiency can be put to test using a very simple technique. A thermometer should be placed almost next to the inlet and the temperature checked. The temperature registered should be the same as that of the air a few feet away.
